I’m aware of the strategy you mention in the context of racial and ethnic diversity, but do you have a source suggesting that cohesion also decreases with more gender diversity, and that governments, corporations, etc. are somehow actively exploiting that? If anything I’d expect the opposite effect to occur.

Just a small empirical experience. No conclusions.

When there are a couple of girls in the class, they all tend to hang out together. Once the ratio goes closer to 1:1, there's a "boys' club" and there's a "girls' club".
